IMPROVEMENT IN WATER- METERS.

Specification forming part of Letters Patent No. 222,607, dated December 16, 1879; application filed October 13, 1879.

' spondin g cylinders radiating from a common central chamber; and it consists, first, of three pistons operating in corresponding cylinders, and provided with connecting=rods, combined with a rotary valve and its seat, both of which are provided with ports made proportional to the number of cylinders, and arranged in relation thereto with reference to position, as will be more fully described.

It also consists of a removable valve-seat held in'place by a pin or screw, and having horizontal segmental divisions or compartfments, separated by partitions, with ports through the upper side communicating with said compartments, and having a central hole, through which, or through a tube attached to the valve and inserted therein, the water is conducted from the cylinders, when it is measured, into the exhaust-chamber below.

It also consists of a tube attached to the valve and extending down through the valveseat, said tube being provided with openings made at an angle to the axis of the tube,

whereby the water flowing out through said openings assists the rotation of the valve.

It also consists of an exhaust-chamber made below the cylinders, valve, and valve-seat, and

provided with an outlet at the bottom, whereby all the sediment passing into the machine is carried down through the valve into the eX- haust-chamber, and thence out through the outlet.

It also consists of a piston having a recess or cavity made therein, with a pin secured in the piston, or a projection cast therein and projecting into said recess or cavity, combined with a piston-rod having a hole in the end, so

that the rod may be hooked into the piston, all which will be more fully hereinafter described.

Fig. II is a vertical section of the same at line F of Fig. I, showing the arrangement of the ports, and also the connection of the rods with the pistons and the wrist-pin of the valve. is a vertical section at line H of Fig. I, showing the position of the valve and valve-seat with reference to the inlet and outlet and the exhaust-chamber. Fig. IV is a reverse plan view of the valve. Fig. V is a plan view of the valve-seat. Fig. V1 is a reverse plan view of the valve-seat. Fig. VIIis a horizontal section of the valve-seat through the segmental compartments. Fig. VIII is a plan view of a part of the connecting-rod, showing the segmental eye which is attached to the wrist-pin. Fig. 1X is a side view of the same. Fig. X is a side view showing the wrist-pin and the rings which secure the ends of the connecting-rods thereto; and Fig. XI is a horizontal section of the tube attached to the lower side of the valve, showing the inclined openings made therein.

In the drawings, A A represent the cylinders, three in number, arranged in a series radiating from a. common center or chamber,

and these cylinders are supported upon a base, H, inside of which is the exhaust-chamber I. At theupper end of this chamber isa shoulder, 8, upon which rests the valve-seat D, which is held in place by a screw or pin, m. This valve-seat 1) contains three horizontal compartments, a, corresponding in number with the cylinders, which compartments are equal in size, and are separated one from the other by the partitions 1, (shown in Fig. VII;) and the upper part of this valve-seat is provided with three ports, 0, also equalin size, and corresponding in number with the cylinders and compartments, and which are made through the top of the valve-seat, each opening into a corresponding compartment, n, beneath. These ports 0, being of any given width, are each equal in length to one-sixth of the entire length Fries.

around the valve-seat in the line of said ports, with a solid portion between each two of the same length, or one-sixth, and the valve-seat is provided with a central hole, D

The valve D is provided with a port, 43, of twice the length of the ports 0, or of two-siXths of the entire length around the valve D in the down into the central hole in the valve-seat;

but we prefer'to make it in the form of a tube, with its lower end resting upon a set-screw,

H, in the bottom of the exhaust-chamber I, and with the openings fmade in said tube,

opening from the passage D inside, out into the chamber I. These openings we make at an angle with the axis of the tube, as shown in Fig. XI, to assist the valve in rotating. The lower side of this valve D is made flat, or upon a plane corresponding to the top of the valve-seat, and parallel with it, so as to fit it properly, and is provided with a'port, 41, corresponding in size and form with the port 1 and opening through the lower part of the alve into the port or passage D The length of each port 1' and t" is two-sixths of the whole distance around the valve on the line of said ports, with a solid part of one-sixth of 'said This arrangement of the valve and valve-seat, and proportion of ports therein, always gives a clear water-way of an area equal to the area of one of the ports 0, no matter in what position the ports i and i may be with reference to the ports 0, any or all of them.

Each piston B we provide with a recess, a, with a pin or projection, to, fixedtherein; and the corresponding end of the rod 0 has a hole therein, so that the rods are secured to the pistons by inserting their ends into the recesses or cavities a, above the pins, and dropping them so that the pins will enter the holes, the rods-(J resting upon the shoulder at the bottom of the recess. Of course the rods may be connected to the pistons by any of the ordinary and well known means; but we find this method very simple, cheap, and effective. The opposite end of each piston-rod may be connected with the wrist-pin 0 of the valve by a segment, h, made on each rod, and placed against the wrist-pin, with one or more rings slipped on over the segments, as shown in the drawings; or they may be attached by any other well-known means, this feature of the segment and rings not being an essential fea ture of our invention.

The inlet is shown at E, by which the water is admitted to the chamber or space above the valve and to the inside of the pistons, and E is the outlet through which the measured water is taken from the exhaust'chamber below the valve.

The operation of our invention is as follows: The water, being admitted through the inlet E, passes into the chamber or space above the valve and between the pistons, and forces the latter outward, causing the valve to rotate in and upon the valve-seat D. As each piston is drawn inward by the rotation of the valve D the port 1' through the valve coincides with one of the ports 0 through the upper part of the valve-seat, and as this port 0 opens into the compartment 42, and the latter communicates with the passage 0 below the cylinder, the live water passes down through the ports 6 and 0 into and through the compartment at and passage 0 into the outer end of the cylinder until the piston has reached'the inner end of its stroke, this position of the piston, valve, and ports being shown in Figs. I and II. During this inward movement of the piston the exhaust-port i, in thclower part of the valve, is in communication with the other two ports o,'and the live water which filled the outer ends of the cylinders outside the pistons is forced by the outward movement of the pistons back through the passage 0, up through the exhaust-port t" into the tube D and thence out through the openings f into the exhaustcha-mber I, and out through the outlet E As the water passes out through the openings f it flows against the widest or inclined side of eachopening, and operates thereby to assist the valve in making its rotary movement.

It will be seen that the live water is always on both sides of the pistons, so that they are always perfectly balanced and move with the greatest ease.

When the exhaust-port e" in the valve communicates with any of the ports 0 in the valveseat, the water which fills the outer end of the cylinders corresponding to those ports is thereby measured, (each cylinder holding a certain quantity,) and is free to pass out, the

live water above the valve and inside the pistons operating to force the pistons outward whenever the exhaust-port t" is in position to permit the water on the outside of either piston to pass down into the exhaust-chamber I and out through the outlet E The screw H, upon which the lower end of the tube D has a bearing in the bottom of the exhaust-chamber, may be turned either up or down, toadjust the valve and its seat to the desired degree of contact 5 and the registering mechanism may be connected with the wristpin a, or with the tube D if desired, in any convenient manner to indicate the number of revolutions of the valve.

If anyof the parts of the meter,'constructed as above described, should require repairs, it is only necessary to remove the cap L; and the wrist-pin, its rings, the connecting-rods, pistons, and the valve may all be readily removed. and by loosening the screw m the valve-seat may also be removed, so that all the parts are easily removed by simply taking off the cap L.

Having thus described our invention, what we claim as new is 1. In combination with the pistons B, the valve D, provided With the ports 2 and i, and the tube or Water-passage D and the valveseat D, provided with the ports 0 and compartments n, all constructed substantially as and for the purpose described.

2. In a Water-meter, the removable valveseat D, provided with the ports 0, and with the horizontal compartments n, separated one from the other by the partitions Z, and the central hole, D in combinationwith a pin or screw, m, for securing the said valve-seat in position, substantially as herein described.

3. The valve 1), provided with the portsi and t, and the tube or Water-passage D provided with the openings f, made at an angle to the axis of said tube, substantially as and for the purpose herein set forth.

4. In combination with the three cylinders A, the valve D, and valve seat D, with theinlet E, above said valve, and the exhaust-chamher I, provided with the outlet E below said valve and valve-seat, whereby all the sediment that enters the meter is carried out at the bottom of the machine, substantially as set forth.

5. The piston B, having a recess or cavity, a, therein, and provided with the projection or pina, in combination with a connecting-rod, 0, provided with a hole at the end, whereby the rod is connected to the piston by inserting said projection or pin into said hole, substantially as specified.

6. The valve-seat D, provided with ports 0, and with the compartments n, separated by the partitions l, and the central hole, D and adapted to be used in connection with a-rotary valve, substantially as described.
